- Update config to doxygen 1.5.2 (I use this with 1.5.9).
- Add linprocfs and linsysfs to the linuxulator dox.
- Take the generated includes from the .m files from a subdirectory
instead of putting everything into $(.OBJDIR). This imporves the
human readbility of the source directory contents a lot, if you do not
create a separate OBJDIR.
- Assume UTF-8 encoding for every input file.
- Strip the source and dest path from the output, we are not interested
in the absolute location on the machine where the docs are created,
relative the the root of the FreeBSD source is what interests us.
- Exclude .svn directories.
- Switch to alphabetic index.
- Use one line per INCLUDE_PATH member in the common dox-config.
- Bump the __FreeBSD__ version to 9. [here in the MFC: to 8]
- Switch from hardcoded .m files to an run-time generated one. Takes
a little bit more time to get started with actual work, but at least
is more future-proof. If you generate dox for all subsystems, the
time to find all .m files in the source is magnitutes lower than
producing the docs.
- Make the *DEST_PATH overidable from the environment. This allows to
produce the output directly in the docroot of a webserver.
- Fix the path when telling the user where he can find the API docs.

Fix the conformance of poll(2) for sockets after r195423 by
returning POLLHUP instead of POLLIN for several cases. Now, the
tools/regression/poll results for FreeBSD are closer to that of the
Solaris and Linux.
Also, improve the POSIX conformance by explicitely clearing POLLOUT
when POLLHUP is reported in pollscan(), making the fix global.

Fix poll() on half-closed sockets, while retaining POLLHUP for fifos.
This reverts part of r196460, so that sockets only return POLLHUP if both
directions are closed/error. Fifos get POLLHUP by closing the unused
direction immediately after creating the sockets.
The tools/regression/poll/*poll.c tests now pass except for two other
things:
- if POLLHUP is returned, POLLIN is always returned as well instead of
only when there is data left in the buffer to be read
- fifo old/new reader distinction does not work the way POSIX specs it

Bugfix: all requests for creating vnets via vimage -c were always
reported as failures, even if the actual library / system call
would succeed, because error message would be reported if the return
value from jail_setv() call was >= 0, and if not, then if that same
value was < 0, i.e. always. The correct behavior is to abort (only)
if jail_setv() returns < 0.

vimage(8) is a legacy CLI interface for managing jails associated with
network stack instances, which is provided for compatibility with
older applications. This change brings it back to life in a followup
to the initial conversion of vimage to use the new jail(4)
userland-kernel API:
- when creating vimages via "vimage -c", by default turn on a few
options expected by legacy applications, such as allow operations on
raw sockets, FS mounts etc, and allow jail-related parameters to be
optionally configured.
- introduce the "-m" modifier which allows for configuring jail
parameters of existing vimages / vnet-jails.
- make "vimage name command ..." actually work.
- when reassigning ifnets to vnets using "vimage -i", attempt to rename
the ifnet as "ethXXX" on arrival in the target vnet. Several legacy
applications are known to depend heavily on such behavior.
- vimage -l lists only jails associated with vnets. The output is
sorted using vimage / jail names as keys.
- vimage -l by default searches only the current level in the jail
hierarchy. Recursive listing can be requested via -r switch.
- vimage -l by default prints only jail names on each line, making
such output suitable for pipelining to other commands. More verbose
output can be obtained via -v switch, and even more jail specific
information will be displayed if -j switch is turned on.
- there's no need to build vimage as statically linked, so update the
Makefile accordingly.
- update the vimage.8 man page.

Make regression/priv compile again after the multi-IP jail

rather than the jail_set(2)/jail(3) syscall.
Add an IPv4, and an IPv6 loopback address in case we compile

net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.
Authentication and encryption are not implemented.
There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).
A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.
Drivers that support mesh networks right now are: ath, ral and mwl.
More information at: http://wiki.freebsd.org/WifiMesh
Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.
Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

NANO_DISKIMGDIR.
- Simplify an 'if (not wrong); then true; else action; fi' into

Note: Make sure you use NANO_OBJ were you use MAKEOBJDIRPREFIX now in your

It is possible to ask nanobsd.sh to create a 'data' partition,
separate from the system or configuration partitions, and
furthermore, by specifying a negative value for its size
to request that it use all space unused by those partitions
for its own size.
Because the two lines of code that calculate how much space
is available for this data partition are written in perl-like
syntax, the awk code that does the processing performs the
calculation incorrectly.
[note - this was already fixed by r174936]
Furthermore, a comparison later down fails to newfs the
partition when the size is negative.

any open file descriptors >= 'lowfd'. It is largely identical to the same
function on other operating systems such as Solaris, DFly, NetBSD, and
OpenBSD. One difference from other *BSD is that this closefrom() does not
fail with any errors. In practice, while the manpages for NetBSD and
OpenBSD claim that they return EINTR, they ignore internal errors from
close() and never return EINTR. DFly does return EINTR, but for the common
use case (closing fd's prior to execve()), the caller really wants all
fd's closed and returning EINTR just forces callers to call closefrom() in
a loop until it stops failing.
Note that this implementation of closefrom(2) does not make any effort to
resolve userland races with open(2) in other threads. As such, it is not
multithread safe.

I found out that the input format of the Boemler list was different
than what the code expected: The last two fields were interpreted
as one. Checking the csv version of the list it showed that there
was sometimes a chipset number in the column before the card

This is a rewrite to use the CSV format of the Boemler list. The
output is differently formatted: Instead of the "chip description",
it is now "description (chip)"
